Everyone probably remembers this piece by Sergei Prokofiev from their childhood. For those of you who don't remember, it's the piece that has an instrument represent each character:
Bird : flute
Duck : oboe
Cat : clarinet
Grandfather : bassoon
Wolf : horns
Hunters : Woodwinds
Peter : string instruments
And some percussion thrown into the mix.
It's programmatic music, which basically means that it is music which tells a story. In this case, it's about a boy named Peter and some animals he befriends who get attacked by a wolf. Spoiler alert: The duck DIES!? What the HECK! That's not the Peter and the Wolf I remembered. Anyway, it's a cute story. It's well worth listening to, as there are spots guaranteed to make you smile, such as the grandpa's lethargic bassoon entrance.
